Overview
EN 293:1992 (CEN) specifies the minimum requirements and testing for oil pressure atomizing nozzles without backflow - referred to as atomizing nozzles - intended for use with fuel oil. The standard applies to nozzles with a nominal throughput ≤ 6.30 kg/h at 10 bar. EN 293 is focused on ensuring correct operational function (see clause 5) and provides a harmonized baseline for performance, reliability, and safety of small-capacity oil atomizing nozzles used in burners.
Key Topics and Requirements
- Scope and definitions: clear delimitation to oil pressure atomizing nozzles without backflow and the specified nominal throughput and pressure rating.
- Minimum functional requirements: criteria that the nozzle must meet to be considered operationally acceptable (EN 293 emphasizes functional performance as described in clause 5).
- Testing principles: procedures and acceptance checks to verify that the nozzle performs reliably under specified operating conditions (flow/pressure class stated in the scope).
- Performance consistency: requirement for repeatable and measurable operation at the specified throughput and pressure, minimizing variability between units.
- Safety and integrity aspects: ensuring no backflow and maintaining nozzle sealing and operational stability during use.
- Reference to burner category: aligned with ICS 27.060.10 (liquid and solid fuel burners), positioning the nozzle requirements within burner systems.
Applications
EN 293 is intended for practical use in contexts where small-capacity oil atomizing nozzles are installed or supplied:
- Domestic and light commercial fuel-oil burners for heating systems
- Component specification for burner manufacturers and OEMs
- Quality control and incoming inspection for nozzle manufacturers and suppliers
- Type testing by accredited laboratories and conformity assessment bodies
- Maintenance and replacement guidance for HVAC and boiler service providers
Who Uses This Standard
- Nozzle and burner manufacturers seeking harmonized minimum requirements
- Product designers and R&D teams developing fuel-oil atomizing components
- Test laboratories performing functional and conformity testing
- Certification and regulatory bodies assessing compliance for heating equipment
- Installers and maintenance engineers specifying replacement nozzles
Related Standards
EN 293 sits within the family of standards for burners and combustion equipment (ICS 27.060.10). For complete system compliance, users typically consult other CEN/ISO standards covering burner performance, safety, and combustion testing.
